Chapter 4
"So what do we do?", Ron muttered to Harry, after he had told him what happened. They were bent over their cauldrons, both eyeing Hermione. "I don't know", Harry whispered back, thinking. It would by far exceed his abilities to concoct an antidote for an unclassified love potion. He supposed Slughorn would be able to do it, but then that might lead to all sorts of trouble... and Hermione hadn't done or even said anything unusual yet. Maybe the potion was a fluke? Maybe it wasn't even working? He shared his theories with Ron, who agreed.
"Who is that potion even for, supposedly?", Harry asked aloud, after class was over and Hermione had left. Ron shrugged. "They wouldn't say. Some bullshit about a lady's privacy. As if that will matter, if we don't find a way to stop this thing if it does kick in." It was Harry's turn to agree with Ron. To him, Hermione had never shown an overt interest in anybody- the only thing she was interested in were her classes.
Then a dangerous idea came into his head, the kind of idea that usually got him within an inch of being kicked out of Hogwarts. "Ron", he said lowly, turning his head so that no one would see, "what if we don't have to cure Hermione? What if we simply give a potion to her crush, whoever that is, as well?" Ron looked at Harry for a moment, before both turned to the full cauldron of Amortentia that was happily bubbling in the corner. "We do this as a last resort", Ron said, and Harry nodded.
